简要总结
The purpose of the study was to assess the effects of participation in an online Mindfulness-Based Stress Reduction (MBSR) program on everyday memories of personal past events in individuals with depression vulnerability. Previous research has demonstrated that individuals with depression experience various difficulties when thinking about personal past events, such as more intense negative emotions, difficulties in regulating their emotions, and difficulties in recalling highly contextualized and detailed events. Some of these difficulties may continue following recovery from depression and as such may constitute a vulnerability for recurring depression. Other studies have found that mindfulness-based interventions (MBIs) may influence how people experience and regulate their emotions, and certain aspects of how people remember personal past events. Therefore, it is possible that MBIs may also influence how individuals with depression vulnerability emotionally process memories of personal past events. In the present study participants with a history of depression were allocated to either an 8-week online MBSR condition where participants were introduced to and engaged in different mindfulness practices, or a waitlist-control condition, where participants did not receive any active training or treatment. In order to assess the effects of the MBSR program on everyday memories of personal past events participants were asked to complete a memory diary in which participants recorded both spontaneously arising and word-cued memories of personal past events in everyday life, before and after participating in the MBSR program or the waitlist-control condition. The investigators hypothesized that participants in the MBSR condition would report reduced difficulties related to memories of personal past events compared to the waitlist-control group, including how participants emotionally process these memories. The investigators predicted that these effects would be greater for spontaneously occurring memories than for voluntary memories, since previous research comparing individuals with different levels of mindfulness skills suggests that mindfulness may be especially beneficial for influencing emotion regulation in response to memories that come to mind spontaneously.
详细描述
PRIMARY OBJECTIVE:
I. Determine the effects of an online, self-directed Mindfulness-Based Stress Reduction (MBSR) program on emotion regulation in response to everyday involuntary and voluntary (word-cued) autobiographical memories in individuals with a history of depression
SECONDARY AND EXPLORATORY OBJECTIVES:
I. Determine whether an online, self-directed MBSR program performs similar to MBIs in previous studies in terms of effects on depression symptoms, trait mindfulness, and trait emotion regulation; and whether the effects of this program are similar for trait and state measures of emotion regulation.
II. Determine the effects of an online, self-directed MBSR program on additional aspects of involuntary and voluntary autobiographical memories in individuals with a history of depression, including memory specificity, centrality, and emotional experience in response to the memories.

结局指标
主要结局
Change in the employment of emotion regulation strategies in response to everyday involuntary and voluntary autobiographical memories from baseline to post-intervention
时间窗: Baseline to post-intervention, an average of 11 weeks
Self-rated (1 = Not at all, to 5 = A great deal) memory suppression ("I tried not to keep thinking about it"), expressive suppression ("I controlled my emotion by not expressing it"), reflection ("I analyzed the event to try to understand my feelings"), brooding ("I thought: Why do I always react this way?", cognitive reappraisal ("I changed the way I was thinking about the situation"), and non-reactivity ("I noticed the memory and feelings without having to react to them") in response to autobiographical memories was measured with a naturalistic memory diary method. Participants were asked to record and rate involuntary autobiographical memories in the memory diary immediately upon retrieval, over a period of up to five days or until they had recorded seven memories. For each involuntary memory recorded in the memory diary, participants were instructed to record and rate a word-cued (voluntary) memory when they had time later that day.

- Change in expressive suppression and cognitive reappraisal from baseline to post-intervention(Baseline to post-intervention, an average of 11 weeks)
- Change in trait mindfulness from baseline to post-intervention(Baseline to post-intervention, an average of 11 weeks)
- Change in rumination (brooding, reflection, overall) from baseline to post-intervention(Baseline to post-intervention, an average of 11 weeks)
